A fracture-propagation-control model for pipelines transporting CO2-rich mixtures including a new method for material-model calibration
(Journal article; Peer reviewed, 2017)This work considers a predictive numerical modelling approach for fracture-propagation control in CO2-transport pipelines, an area where current engineering tools do not work. Fluid-structure interaction model simulations ... -
Depressurization of CO2 in a pipe: Effect of initial state on non-equilibrium two-phase flow
(Peer reviewed; Journal article, 2023)It is key in several industrial applications to accurately describe rapid depressurization of liquid and dense phase states. Examples include refrigeration systems, nuclear reactor cooling and capture and storage (CCS). ... -
Depressurization of CO2-rich mixtures in pipes: Two-phase flow modelling and comparison with experiments
(Journal article; Peer reviewed, 2015)We present and discuss two-phase flow models to simulate transient flow of CO2-rich mixtures in pipes, which is of relevance for design, operation and safety. The model predictions are compared to data from five depressurization ... -
Experiments and modelling of two-phase transient flow during pipeline depressurization of CO2 with various N2 compositions
(Journal article; Peer reviewed, 2014)Pressure-release experiments of CO2 with impurity contents of 10, 20 and 30 mol% nitrogen have been executed. The experimental investigations were performed in a 140 m long horizontal tube with an inner diameter of 10 mm. ...
